On closer inspection of Nintendo Land it looks like a lot of the environment shadows are baked. Ergo, not so impressive. Look forward to seeing the final build.
If you don't mind me asking, where are you inspecting this game? Are you just watching a bunch of Youtube vids? I've only seen what little was shown in the press conferences and such.
I'm hoping someone can really point me to a video where it shown something taxing in the game.
